Description

(Cross-reference to related applications)
This application includes US patent application Ser. Nos. 12/489811 and 12/489843 filed Jun. 23, 2009, and US Patent Application No. 12/163116 filed Jun. 27, 2008 and No. 12/16180, which is a continuation-in-part application, each of which is specifically incorporated herein by reference.

(background)
The present invention generally relates to mesogen-containing compounds, formulations thereof, optical elements, liquid crystal polymers, and methods for making the same.

  Liquid crystal (“LC”) molecules tend to align with each other in a preferred direction, resulting in a fluid material having anisotropic optical, electromagnetic, and mechanical properties. Mesogen is the basic unit of LC that induces structural order in liquid crystals.

  A liquid crystal polymer (“LCP”) is a polymer that can form regions of highly ordered structure in the liquid phase. LCP has a wide range of uses, ranging from hard engineering plastics to delicate gels for LC displays. The structure of LCP can consist of dense fibrous polymer chains that provide self-strengthening to near the melting point of the polymer.

  Dichroism can occur in LC due to either the optical anisotropy of the molecular structure or the presence of impurities or the presence of dichroic dyes. As used herein, the term “dichroism” means the ability to absorb at least one of the two components polarized in the plane perpendicular to the transmission line more strongly than the other.

  Conventional linear polarizing elements such as sunglasses and linear polarizing lenses for linear polarizing filters are typically formed from stretched polymer sheets containing a dichroic material such as a dichroic dye. As a result, conventional linear polarization elements are static elements that have a single linear polarization state. Thus, when a conventional linear polarization element is exposed to either randomly polarized or reflected radiation of the appropriate wavelength, a certain percentage of the radiation transmitted through the element is linearly polarized. The As used herein, the term “linearly polarized” means that the vibration of the electrical vector of the light wave is limited to one direction or plane.

  In addition, conventional linear polarizing elements are typically lightly colored. That is, a conventional linear polarizing element contains a colorant (ie, a dichroic material) and has an absorption spectrum that does not fluctuate in response to light irradiation. As used herein, “light irradiation” means electromagnetic radiation, such as ultraviolet and visible light, that can cause a response. The color of a conventional linearly polarizing element depends on the colorant used to form the element, and is most commonly a neutral color (eg, brown or gray). Thus, while conventional linearly polarizing elements are useful for reducing glare of reflected light, due to their shade, they are not suitable for use under certain low light conditions. Furthermore, since conventional linear polarization elements have only a single colored linear polarization state, their ability to store or display information is limited.

  As noted above, conventional linear polarizing elements are typically formed using a sheet of stretched polymer film containing a dichroic material. The term “dichroism” as used herein means that at least one of the two components polarized in the plane perpendicular to the transmission line can be absorbed more strongly than the other. Thus, the dichroic material can preferentially absorb one of the two components polarized in the plane perpendicular to the transmission line, while the molecules of the dichroic material are properly arranged or arranged. If not, net linear polarization of the transmission line is not achieved. That is, due to the random arrangement of the molecules of the dichroic material, the selective absorption by the individual molecules cancels each other and no net or overall linear polarization effect is achieved. Thus, in general, to achieve net linear polarization, it is necessary to properly arrange or arrange the molecules of the dichroic material by alignment with another material.

  In contrast to the dichroic element described above, Formed using conventional thermoreversible photochromic materials, Conventional photochromic elements, such as photochromic lenses, In general, A first state in response to light irradiation; For example, from the “transparent state” to the second state, For example, convert it to “colored state” after that, The first state can be returned in response to the thermal energy. As used herein, the term "photochromic" It means having an absorption spectrum of at least visible light that varies at least in response to light irradiation. Therefore, Conventional photochromic elements are In general, It is well suited for use in both low light conditions and bright conditions. But, Conventional photochromic elements that do not include linear polarizing filters are In general, It is not adapted to linearly polarize the radiation. That is, The absorption ratio of conventional photochromic elements in either state is Generally less than 2. As used herein, the term “absorption ratio” Refers to the ratio of the absorbance of radiation linearly polarized in the first plane to the absorbance of radiation of the same wavelength linearly polarized in a plane orthogonal to the first plane; The first plane is The plane with the highest absorbance is taken. Therefore, Conventional photochromic elements are The glare of reflected light cannot be reduced to the same extent as a conventional linearly polarizing element. Therefore, Photochromic dichroic materials have been developed. What is photochromic dichroic material? Photochromic properties (ie Having at least a visible light absorption spectrum that varies in response to at least light irradiation) and dichroic properties (ie, At least one of the two components polarized in the plane perpendicular to the transmission line, It can absorb more strongly than the other).

  The photochromic material and photochromic dichroic material can be incorporated into a polymer substrate, including substrates or organic materials, such as LCP substrates. As the photochromic material and the photochromic dichroic material change from one state to another, the photochromic compound or molecule of the photochromic dichroic compound conforms from one conformation state to a second conformation state. The formation can change. This conformational change can result in a change in the amount of space occupied by the compound. However, in order for a specific photochromic material and a specific photochromic dichroic material to effectively shift from one state to another, for example, the transition from the transparent state to the colored state, the transition from the colored state to the transparent state, In order to transition from a polarization state to a polarization state and / or from a polarization state to a non-polarization state, the photochromic compound or the photochromic dichroic compound has a compound that is in one conformation state to a second conformation state. Must be in a chemical environment that is sufficiently flexible to allow the transition to a sufficient rate to provide the desired response over an acceptable time frame. Thus, in order to further develop photochromic and photochromic dichroic materials and substrates, new polymer materials such as new LCPs and materials to form these new materials are needed.

(Detailed description of embodiment)
The following describes mesogen-containing compounds and liquid crystal compositions and formulations containing mesogen-containing compounds according to the present disclosure. The mesogen-containing compounds disclosed herein can be used, for example, in optical elements including, for example, liquid crystal polymers ("LCPs"), such as ophthalmic elements, display elements, windows, and mirrors. And new structures that can be used in a variety of applications, including compositions. According to certain aspects of the present disclosure, the mesogen-containing compounds of the present disclosure can serve as monomers for forming LCP.

  A mesogen is a basic unit of liquid crystal (“LC”) that induces structural order in the liquid crystal. The mesogenic portion of the LC typically includes a rigid portion that aligns with other mesogenic components in the LC composition, thereby aligning the LC molecules in one direction. The rigid portion of the mesogen may consist of a rigid molecular structure, such as a monocyclic or polycyclic ring structure including a monocyclic or polycyclic aromatic ring structure. Examples of potential mesogens are further elaborated herein, including Demus et al., “Flushage Kristall in Tablen”, VEB Deutscher Verlagfur Grunstoffindustrie, Leipzig, 1974 The mesogenic compounds described in Grundstoffindustrie, Leipzig, 1984 are included. The LC can also include one or more flexible moieties in the LC molecule. One or more flexible portions may impart fluidity to the LC. LCs can exist in a disordered state or in an ordered (or aligned) state. LC molecules in a disordered state take an essentially random orientation, i.e. there is no overall orientation of the LC molecules. An ordered or aligned LC molecule generally assumes an orientation in which the mesogenic portion of the LC molecule is at least partially aligned throughout the LC material. As used herein, the term “aligned” or “aligned” means proper placement or position by interaction with another material, compound or structure. In certain embodiments, the mesogenic portion of the LC molecule may be at least partially aligned in a parallel orientation. In other embodiments, the mesogenic portion of the LC molecule may be at least partially aligned in a helix orientation, such as in a reflective polarizer.

  The mesogen-containing compounds of the present disclosure can be used for a variety of functions, including LC compositions. The mesogen-containing compounds of the present disclosure can act as non-monomer components, such as non-monomer LC components. As used herein, the term “compound” means a substance formed by the joining of two or more elements, components, components, or parts, and refers to two or more elements, components, components, or Included are molecules and macromolecules (eg, polymers and oligomers) formed by the joining of moieties. Compositions formed from mesogen-containing compounds can be used as layers such as cured coatings and films on at least a portion of the substrate that can impart certain desired characteristics to the substrate, as well as molded articles, assemblies, and cast articles. It can have a variety of uses, including use as a product. For example, compositions formed from mesogen-containing compounds can be used, for example, in optical data storage applications, as photomasks, as decorative pigments, in cosmetics and for security applications (eg, US Pat. No. 6,217). 948) as a curable resin for medical, dentistry, adhesive and stereolithography applications (see, eg, US Pat. No. 7,238,831) in the aforementioned applications and various related devices. Can be used as at least a partial layer, coating or film on at least a portion of the substrate that can impart certain desired characteristics to the substrate, such as as a product such as a molded, assembled, or cast article for use .

  Mesogen-containing compositions are optical elements such as ophthalmic elements, display elements, windows, mirrors, active and passive liquid crystal cells, elements and devices, and other LC or LCP-containing objects such as polarizers, light Compensators (see, eg, US Pat. No. 7,169,448), light suppressors (see, eg, US Reissue Patent RE39,605 E), color filters, and wave plates for lightwave circuits (eg, US Pat. No. 7,058,249) or can be incorporated into LC and / or LCP that can be incorporated therein. For example, LCP can be used to form optical films such as inhibitors, waveguides, reflectors, circular polarizers, wide viewing angle films. Specific embodiments of mesogen-containing compounds may find specific use to form ophthalmic elements further comprising at least one photochromic or photochromic dichroic material or compound. As described in further detail herein, mesogen-containing materials of various embodiments of the present disclosure provide desired kinetic properties for certain photochromic or photochromic dichroic materials such as ophthalmic elements and optical elements. It may be particularly appropriate to give. In other embodiments, LCP may also be used as a host material for dyes such as photosensitive and non-photosensitive materials. Photosensitive materials include thermally and non-thermally reversible materials, organic photochromic materials such as photochromic / dichroic materials, inorganic photochromic materials, fluorescent or phosphorescent materials, and nonlinear optical materials (“NLO”) Can be. Non-photosensitive materials can include fixed color dyes, dichroic materials, thermochromic materials, and pigments.

  The mesogen-containing compounds of the present disclosure may generally be linear bonds of 1 to 500 atoms in length, for example to form LCP, and thus act as LC and exhibit LC properties or It comprises at least one mesogenic unit and at least one flexible linking group that may be incorporated into a material or composition that can be used as an LC monomer.

  According to one embodiment, mesogen-containing compounds of the present disclosure can be represented by compounds having Formula I.

式Ｉ中、それぞれのＸは、独立して、（ｉ）−Ｒ基、（ｉｉ）構造−（Ｌ）_ｙ−Ｒによって表される基、（ｉｉｉ）構造−（Ｌ）−Ｒによって表される基、（ｖｉ）構造

In formula I, each X is independently represented by (i) -R group, (ii) structure- (L) _y- R group, (iii) structure- (L) -R. (Vi) structure

によって表される基、または（ｖ）−（Ｌ）_ｙ−Ｐによって表される基によって表され得る。さらに、式Ｉ中、それぞれのＰ基は、上記定義した基を表す。

Or a group represented by (v)-(L) _y -P. Further, in formula I, each P group represents a group as defined above.

As described herein, with reference to Formula I, an L group, (L) _y or (L) _w is connected to 2 to 3 groups, typically 1 to 500 Represents a linking group having a linear length of atomic bonds. That is, for general structure FLE, the linkage between F and E groups, where F and E groups can each generally represent any of P, R, X, or mesogenic groups, respectively. The longest linear length of the group can range from 1 to 500 bonds (including intervening atoms). When discussing the linear length of a linking group, the length of the linking group is occupied by the length of each bond in the linear sequence and the various intervening atoms in the linear sequence of the linking group. It will be understood that those skilled in the art will understand that the distance can be calculated by summing the values. In certain embodiments, the longest linear sequence of bonds can be at least 25 bonds between linked groups. In other embodiments, the longest linear sequence of bonds can be at least 30 bonds. In still other embodiments, the longest linear sequence of bonds can be at least 50 bonds. In certain embodiments, it has been determined that a linking group L having at least 25 bonds improves various advantages of the resulting mesogen-containing compound. For example, a linking group of at least 25 bonds may provide faster or improved alignment properties of a composition comprising a mesogen containing compound that may improve the solubility of additives such as photochromic compounds in the composition comprising the mesogen containing compound. The viscosity of a composition that can be provided and / or contains a mesogen-containing compound can be reduced.

Each L group may be the same or different and each occurrence may be independently selected from a single bond, multiple substitution, mono- or unsubstituted spacer as defined above. “W” is represented by the integers 1-26, “y” is represented by the integers 2-25, and “z” is either 1 or 2. When a plurality of L groups appear in succession, for example, in the structure (L) _y or (L) _w where “y” and / or “w” is an integer greater than 1, adjacent L groups are the same It should be understood that the structure may or may not have. Thus, for example, in a linking group having the structure — (L) ₃ — or —LLL— (ie where “y” or “w” is 3), each —L— group is It may be independently selected from any of the aforementioned L groups, and adjacent -L- groups may or may not have the same structure. For example, in one exemplary embodiment, -L-L-L-it is, _- (C 1 _{-C 30)} alkylene _- (C 1 _{-C 30)} alkylene _- (C 1 _{-C 30)} alkylene - a represents obtained (i.e., represented by _(C 1 _{-C 30)} alkylene every time -L- appear, respective adjacent _(C 1 _{-C 30)} alkylene groups have a carbon of the same or a different number in the alkylene radical Can do). In another exemplary embodiment, -L-L-L-is - arylene _- (C 1 _{-C 30)} alkyl silylene _- (C 1 _{-C 30)} alkenoxy - may represent (i.e.,-L-is Each occurrence is different from the adjacent -L- group). Thus, the structure of (L) _y or (L) _w is such that some or all of the adjacent -L- groups are the same, and all adjacent -L- groups are different (but any two It should be understood as covering all possible combinations of various sequences of the linking group -L-, including arylene groups also not linked by a single bond. L can also be trivalent so that it can serve as a group that can be connected to other L groups and P, R, X and / or mesogenic groups.

  With further reference to Formula I, the mesogen-1 and mesogen-2 groups are each independently a strong straight rod-like liquid crystal group, a strong bent rod-like liquid crystal group, or a strong disc-like liquid crystal group. It is. The structure of mesogen-1 and mesogen-2 can be determined by any suitable mesogenic group known in the art, such as Demus et al. It can be any of those described in "Tabelen II", VEB Deutscher Verlag fur Grundstoffindustrie, Leipzig, 1984. Further, according to certain embodiments, the mesogen-1 group and the mesogen-2 group may independently have a structure represented by:

The term “softer” as used herein with respect to characteristics of cured compositions such as LCPs, layers, coatings, and coated articles made from compounds, is typically less than 150 Newtons / mm ² , eg, 0 Refers to a composition exhibiting a Fisher microhardness of ˜149.9 Newtons / mm ² . Cured compositions having a softer structure may exhibit desirable or improved characteristics, such as improved LC characteristics, improved photochromic performance, and improved dichroic performance. For example, in a curable composition such as a polymer, copolymer or mixture of (co) polymers, it may be desirable to have hard and soft areas or components in the polymer. The concept that a cured polymer can be composed of hard and soft areas or components is known in the art (eg, “Structure-Property-Relationship in Polyurethanes”, Polyethane Handbook, edited by G.

Can be determined. The physical properties of a polymer are derived from its molecular structure and are driven by the choice of building blocks, for example, the choice of monomers and other reactants, additives, the ratio of hard and soft areas, and atomic interactions between polymer chains. Determined by the supramolecular structure. Materials and methods for preparing polymers such as polyurethane are described in Ullmann's Encyclopedia of Industrial Chemistry, 5th edition, 1992, A21, 665-716.

Is believed to provide the structural integrity of and / or prevent transfer of convertible compounds. In one application of photochromic and / or dichroic materials, the desired advantage of a suitable curable material or layer or coating, i.e. in the range of 0-150 Newtons / mm < ² >, due to the balance of soft and hard components in the polymer A material, layer, or coating that has a Fischer microhardness and that also exhibits good photochromic and / or dichroic response characteristics can be achieved. In another application, the photochromic and / or dichroic material is in a cured polymeric material having a Fisher microhardness of less than 60 Newton / mm ² , such as 0-59.9 Newton / mm ² , or 5-25 N / mm ^2. And coated with or contained within a harder polymeric material that provides structural strength. In further applications, the photochromic and / or dichroic material is incorporated into a hard polymer coating or material, eg, a material having a Fisher microhardness of greater than 150 Newtons / mm ² , such as 200 Newtons / mm ² or greater. It may already be present in a soft polymer material, such as a soft polymer shell.

  FIG. 6 shows a mesogen with two reactive groups at both ends of the molecule. Soft chains were developed from both ends of the mesogen either by Lewis acid catalyzed processes using excess caprolactone or by base catalyzed processes. This product was then reacted with propionyl chloride to form non-reactive end groups. As described above, this reaction is not limited to propionyl chloride. The product is represented by Formula I when z is 1 or Formulas III and VI.

  FIG. 7 illustrates a method of forming a branched soft chain. In this approach, one of the three commercially available triol-derived hydroxyls was reacted with mesogens using Stegrich esterification. The other two hydroxyls were used to develop soft polycaprolactone chains by a Lewis acid catalyzed process using excess caprolactone. This product was reacted with propionyl chloride to form non-reactive end groups. As described above, this reaction is not limited to propionyl chloride. The resulting product has a branched structure in L and is represented by Formula I when z is 1, or Formulas II, III and VI.

  In other embodiments, the LC composition of the present disclosure may comprise a dichroic compound. Suitable dichroic compounds are described in detail in patent 7,097,303 at column 7, lines 6-60. Other examples of suitable conventional dichroic compounds include azomethine, indigoid, thioindigoid, merocyanine, indane, quinophthalone dye, perylene, phthaloperine, triphenodioxazine, indoloquinoxaline, imidazo-triazine, tetrazine, azo And (poly) azo dyes, benzoquinone, naphthoquinone, anthroquinone and (poly) anthroquinone, antropyrimidinone, iodine and iodate. In another embodiment, the dichroic material can be a polymerizable dichroic compound. That is, according to this embodiment, the dichroic material can include at least one group that can be polymerized (ie, a “polymerizable group” or “reactive group”). For example, in one embodiment, the at least one dichroic compound can have at least one alkoxy, polyalkoxy, alkyl, or polyalkyl substituent terminated with at least one polymerizable group. The term “dichroism” as used herein means that at least one of the two components polarized in the plane perpendicular to the transmission line can be absorbed more strongly than the other. As used herein, the terms “linearly polarized” or “linearly polarized” mean that the vibration of the electrical vector of the light wave is limited to one direction. Thus, the dichroic dye can absorb one of the two components polarized in the orthogonal plane of the transmission line more strongly than the other, thus resulting in a linear polarization of the transmission line. However, while a dichroic dye can preferentially absorb one of the two components polarized in the plane perpendicular to the transmission line, while the molecules of the dichroic dye are not aligned, Net linear polarization of the transmission line is not achieved. That is, due to the random arrangement of the molecules of the dichroic dye, the selective absorption by the individual molecules may cancel each other and the net or overall linear polarization effect may not be achieved. Therefore, it is generally necessary to align dichroic dye molecules to achieve net linear polarization.

  Still other embodiments of the LC compositions herein can include photochromic dichroic compounds. As used herein, the term “photochromic dichroism” means to exhibit both photochromic and dichroic (ie, linearly polarized) characteristics under certain conditions, which are at least detected by instrumentation. Is possible. Thus, a “photochromic dichroic compound” is a compound that exhibits both photochromic and dichroic (ie, linearly polarized) properties under certain conditions, and the properties can be detected at least by instrumentation. Therefore, the photochromic dichroic compound has at least a visible light absorption spectrum that fluctuates in response to light irradiation, and at least one of the two components polarized in the plane perpendicular to the transmission line is replaced with the other. Can absorb more strongly. Thus, like the conventional photochromic compounds described above, the photochromic dichroic compounds disclosed herein can be thermoreversible. That is, the photochromic dichroic compound can switch from the first state to the second state in response to light irradiation and return to the first state in response to thermal energy.

  Further, according to various embodiments disclosed herein, the mesogen-containing material comprises the at least one photochromic compound, dichroic compound, or photochromic dichroic compound from the first state at a desired rate. It can be adapted to allow switching to two states. In general, conventional photochromic / dichroic compounds can be converted from one isomer to another in response to light irradiation, each isomer having a characteristic absorption spectrum and / or polarization. Has features. Photochromic compounds, dichroic compounds, or photochromic dichroic compounds according to various embodiments disclosed herein undergo similar isomer transformations. The rate or speed at which this isomer conversion (and reverse conversion) occurs is partly due to the photochromic compound, dichroic compound, or the cured layer (ie, “host”) comprising the mesogen-containing compound surrounding the photochromic dichroic compound. Depends on characteristics. We believe that the conversion rate of the photochromic / dichroic compound depends, in part, on the flexibility of the host chain area, ie, the mobility or viscosity of the host chain area. Specifically, the conversion rate of a photochromic compound, a dichroic compound, or a photochromic dichroic compound is generally considered to be faster for a host having a flexible chain area than a host having a hard or strong chain area. ing. Thus, according to certain embodiments disclosed herein, where the at least partial layer comprising a composition comprising a mesogen-containing compound is a host, the composition is a photochromic compound, dichroic compound, or photochromic It can be adapted to allow the dichroic compound to convert between various isomeric states at the desired rate. For example, the composition can be adapted by adjusting one or more of the molecular weight and crosslink density of the mesogen-containing compound or residue thereof.

  For example, according to various embodiments disclosed herein, the at least one photochromic dichroic compound has a first state having a first absorption spectrum, a second state different from the first absorption spectrum. Having a second state having an absorption spectrum, adapted to switch from the first state to the second state in response to at least light irradiation and to return to the first state in response to thermal energy; Can do. Further, the photochromic dichroic compound can be dichroic (ie, linearly polarized) in one or both of the first state and the second state. For example, although not required, the photochromic dichroic compound can be linearly polarized in the active state and unpolarized in the bleached or faded (ie, inactive) state. As used herein, the term “active state” refers to a state in which at least a portion of the photochromic dichroic compound has been exposed to sufficient irradiation to cause the first state to switch to the second state. A photochromic dichroic compound. Further, although not required, the photochromic dichroic compound can be dichroic in both the first and second states. For example, photochromic dichroic compounds can linearly polarize visible light in both active and bleached states. Furthermore, the photochromic dichroic compound can linearly polarize visible light in the active state and linearly polarize UV radiation in the bleached state. Examples of suitable photochromic dichroic compounds that can be included in the LC compositions described herein are those disclosed in paragraphs [0089]-[0339] of US Patent Application Publication No. 2005/0012998.

Example 4
Measurement of Melting Point and Liquid Crystal Phase Transition Temperature Each 0.1-5 mg sample of Examples 1-3 was applied to a VWR Vista Vision ™ microscope slide. A FISHHERFINEEST® premium cover glass was applied to the sample. The resulting microscope slide was placed on the hot stage of INSTEC® HCS302 mounted on the sample stage of the OLYMPUS® BX51 polarizing microscope so that the sample spot was in the optical path of the microscope. Further, the microscope was equipped with an INSTEC (registered trademark) STC200 temperature control device so that the hot stage temperature was controlled, and a DIAGNOSTIC INSTRUMENTS 11.2 color mosaic camera so that the phase transition could be observed from a computer display. The melting point of the non-liquid crystal material and the phase transition temperature of the liquid crystal material were measured by observing the sample being heated starting at 25 ° C. at a rate of 1 ° C./min. Unless indicated, melting points and phases below 25 ° C. were not determined. In some examples, as shown in Table 2, to determine the phase transition temperature during the cooling process, the sample was heated until it reached an isotropic phase and then cooled at 1 ° C./min. The phase of the liquid crystal was determined according to the texture that appeared during the heating and cooling process. Textures of Liquid Crystals, Dietrich Demus and Lothar Richter, Verlag Chemie Publishing, Weinheim and New York, 1978 were used to identify the various liquid crystal phases listed in Table 2.

以下の略記を表中で用いた：Ｎはネマチック相を表し、Ｉは等方性の相を表し、Ｋは結晶構造を表し、Ｇｌａｓｓは秩序構造を有さない非晶質状態を表す。すべての数字は、隣接する相の略記が起こった温度を℃で表すことに注意されたい。測定したそれぞれの相は／／によって隔て、これは、記載した次の温度または温度範囲まで相が及んでいたことを意味する。別段に指摘しない限りは、試料の相の観察は室温（２５℃）で開始し、次の相転移温度を報告した。

The following abbreviations were used in the table: N represents a nematic phase, I represents an isotropic phase, K represents a crystal structure, and Glass represents an amorphous state having no ordered structure. Note that all numbers represent in ° C the temperature at which the adjacent phase abbreviation occurred. Each measured phase is separated by //, which means that the phase has reached the next temperature or temperature range described. Unless otherwise indicated, observation of the sample phases started at room temperature (25 ° C.) and reported the next phase transition temperature.
